Backup Manager Cannot Browse Data Mover Server Nodes

Valid on UNIX and Linux platforms.

Symptom:

The Backup Manager cannot browse data mover server nodes. This problem presents itself under the following conditions:

1. The following message appears when you browse data mover nodes from the Backup Manager Source tab.

   Could not reach the agent on the Node. Please check if the agent is installed and running on the machine. Do you want to continue?
   

2. To ensure that the data mover server is communicating via the Common Agent, you execute the following command from the data mover server:

   caagent status
   

   The following message appears, which confirms that the Common Agent is running:

   Checking the CA ARCserve Backup Universal Agent process... It is RUNNING (pid=16272)
   

3. You execute the following command on the data mover server:

   tail –f /opt/CA/ABcmagt/logs/caagentd.log
   

4. From the Backup Manager source tab, you try to browse the data mover node.

   You observe that the caagentd.log file is not updating. The Common Agent is not receiving communication requests from the primary server.

Solution:

Ensure that you add CA ARCserve Backup to the firewall exceptions list on the target data mover server. This will allow the CA ARCserve Backup primary server to communicate with the data mover server after you install UNIX and Linux Data Mover. By default, CA ARCserve Backup communicates using port 6051.

Note: For information about how to add CA ARCserve Backup to the firewall exceptions list, see the platform-specific documentation for the data mover server.
